[. . . ] DSR is one of the handshaking signals for most serial interface cables. The serial interface uses DSR to distinguish data sent by the computer from data created by electrical noise in the serial cable. Select On to prevent stray characters from printing. 7 8* Off* On All data received by the serial port is treated as valid data. Only data received while the DSR signal is high is treated as valid. Job Buffering To temporarily store jobs on the printer hard disk before printing. Note: Changing the Job Buffering menu item automatically resets the printer. Off* On Auto Does not buffer print jobs to the hard disk. Buffers print jobs only if the printer is busy processing data from another input port. 65 Menu Item Purpose To specify whether the printer performs the special processing required for bidirectional communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol. Note: Changing this menu item automatically resets the printer. Values On Printer performs NPA processing. Printer examines the data to determine the format and then processes it appropriately. NPA Mode Off Auto* Parity To select the parity for serial input and output data frames. Even Odd None* Ignore PCL SmartSwitch To configure the printer so it automatically switches to PCL emulation when a print job received through the serial port requires it, regardless of the default printer language. On* Printer examines data on the serial interface and selects PCL emulation if the data indicates that is the required printer language. The printer uses PostScript emulation to process the job if PS SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PS SmartSwitch is Off. Printer examines data on the serial interface and selects PostScript emulation if the data indicates that is the required printer language. The printer uses PCL emulation to process the job if PCL SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PCL SmartSwitch is Off. Printer sends a continuous stream of XONs to the host computer to indicate that the serial port is ready to receive more data. Off PS SmartSwitch To configure the printer so it automatically switches to PostScript emulation when a print job received through the serial port requires it, regardless of the default printer language. On* Off Robust XON To determine whether the printer communicates availability to the computer. This menu item only applies to the serial port if Serial Protocol is set to XON/XOFF. Off* On 66 Menu Item Purpose To configure the size of the serial input buffer. Note: Changing the Serial Buffer menu item automatically resets the printer. Values Disabled Disables job buffering. Any jobs already buffered on the disk are printed before normal processing of incoming jobs resumes. Printer automatically calculates the Serial Buffer size (recommended setting). The maximum size depends on the amount of memory in your printer, the size of the other link buffers, and whether Resource Save is set to On or Off. To maximize the range for the Serial Buffer size, disable or reduce the size of the parallel and USB buffers. Combined hardware and software handshaking. Serial Buffer Auto* 3K to maximum size allowed Serial Protocol To select the hardware and software handshaking values for the serial interface. DTR* DTR/DSR XON/XOFF XON/XOFF/ DTR XONXOFF/ DTRDSR Setup Menu Use the Setup Menu to configure a variety of printer features. Note: Values marked by an asterisk (*) are the factory default settings. Menu Item Purpose To establish whether the printer sounds an alarm when the printer requires operator intervention. Printer does not resume printing until someone clears the error message. Printer waits the specified amount of time, and then automatically resumes printing. [. . . ] The accuracy of the estimates may be affected by how full the print cartridges are, environmental conditions, the media type, the software application, software settings, the driver, driver settings, and the content of the page. Lexmark makes no claim as to the accuracy of the estimated percents. 134 Configuring printer alerts You can configure the printer several ways to let you know when it requires attention. Using the Setup Menu Menu item Alarm Control Function Lets you establish whether the printer sounds an alarm when it requires operator intervention. Value Off Single Continuous Toner Alarm Lets you choose how the printer responds when toner is low. Off Single Continuous Result The alarm does not sound, but printing stops until the interventions are cleared. * The printer stops printing, displays a message, and activates the selected alarm type.
